DC Motor Speed Controller, Thyristorised

Precise Controls

Precise Controls offers a thyristorised DC shunt motor speed controller, in power pack modular construction. The armature voltage is controlled with SCR/diode single-phase full wave half controlled bridge. The SCR/diodes are protected with RC snubbers and MOVs. The power semiconductors are mounted on the aluminium extruded heat sink for cooling. The control circuit is assembled on glass epoxy, PTH printed circuit board. Highly stabilised reference supply, dual ramp circuit, speed loop circuit, current loop circuit, isolated voltage and current feed back signals are incorporated. It is possible to synchronise the speed with other drives through encoders. Power packs are available for 7.5 HP motors. Three-phase full wave fully controlled SCR bridges are available for power packs up to 100 HP DC motors. The power packs are manufactured with a high degree of quality control. These used for printing machines, machine tools, cement plants, etc.
